Now that Paradox own the rights to Prison Architect and Double Eleven are in charge of development, they're continuing the free updates.

The Slammer update was released yesterday and one of the major changes is an overhaul to Deployment. The presentation of visuals of the interface were improved so you can see your prison, you can assign Armed Guards and Dog Handlers to patrols and zones, you can have 2 different intersecting patrol routes plus routes and zones can be prioritized.

New furniture such as new chairs, short benches, short tables will fulfill room requirements.

New Jungle plot and Snowbound plot options added, to start a new prison on.

New Guard Pavillion towers are unlocked for players who sign up for a Paradox account.

There's plenty of other changes like new hotkeys for cycling through options in in-game item menus, more rotations added for older objects, the ability to easily move objects by double clicking and after you move it a worker will sort it, the option to start with everything researched and so on.

The update didn't come without issues on Linux though, as it seems to open the new Paradox Launcher and then instantly quit which isn't great. Although, this problem might be just for newer distributions.

FIX: To make the Paradox Launcher work with the Steam version, add this as launch option (right click -> "Properties" -> "Set Launch Options…"):

LD_PRELOAD=/usr/lib/libc.so.6 %command%

That will make the Paradox Launcher work fine.

If you wish to completely bypass the launcher make sure it has the steam_appid.txt file which it's missing inside the folder where you installed it, all it needs inside is "233450" (the ID of Prison Architect on Steam). To find the folder, right click on the game and go to "Properties" and then -> hit the "Local Files" tab and press "Browse Local Files…". Once done, just run the game directly to bypass the launcher. I've sent a message to Paradox today about the issues.

I had to stop playing a few months ago because the game causes burn-in on my monitor. No idea why, it just leaves a ghost image of the menus, etc. even if I switch to my PS4. It eventually fades away, but it's very distracting when it's present. Might give it another go, just in case it was a driver bug or something.

Launching from terminal...error: missing libsndio6.1 - My distro is on libsndio7.0. Quick copy old lib from another location into the Prison Architect/lib64 dir, ok.error: no appID found - Create steam_appid.txt as described above, ok.

Hey presto, game runs from terminal. Launcher still borked in Steam.

I needed to alter the path to libc thusly.LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libc.so.6 %command%

Yeah, I just finished fighting the game to get it to launch on my system too.

The ancient sndio library dependency comes from the libSDL2-2.0.so.0 the game ships with. I avoided that by preloading /usr/lib/libSDL2-2.0.so.0. Even when preloading /usr/lib/libc.so.6 I can't get the launcher to show up, so I ended up just forcing steam to launch the game binary directly. So, TLDR, I set my launch command in steam to:LD_PRELOAD="/usr/lib/libSDL2-2.0.so.0" ./PrisonArchitect.x86_64 %command%
(That %command% still seems to be needed, despite the "command" being explicitly set...)

I've never had this problem with Prison Architect in the past. It's quite.. disappointing.

If you bought the game direct from Introversion, it seems you are just screwed out of any updates. I know people love Prison Architect but it has always been buggy and incomplete, last thing I'll buy from these guys.

New patch released, The Slammer Hotfix 1.02"Requiring unsupported libraries will no longer crash the game on Linux."
Still needs the same fixes as I posted earlier.
